My 2005 is the same ignition as your 04. #4 was where the Pro-Comm directions said to set it at. But it ran like crap. I just took a chance and tried #5. I also went back to stock NGK plugs! Like I said it runs better now than the bike has in 5 years. No more Decel popping, I actually miss that. Evryone knew it was me coming down the street when it popped. Now I'm in Stealth mode.

I couldn't handle not having my decel popping.

I LOVE IT!

I'm ordering one this weekend. Of course I'll be going right to setting 10. Maybe it will be too much, what do they consider modified? 904, headwork, carbs, intakes, blah blah... Is 10 for a stroker? I just need to make sure my ignitor numbers match before I order it. I'll be doing a dyno run soon after to see if it makes a big difference anywhere in the power curve.

ok might be ordering a cdi soon but the part# is missing on my stock cdi box any know what it is supposed to be 2005 america vin# 216483

03 speedmaster, k&n pods, 155 mains, drilled slide,tps unpluged. Running position #7 and default map at the moment. No problems so far.

Was it ever determined that the TPS needs to be hooked up for this to work properly? I just installed mine and it wants to be fully choked to start with default map, TPS unhooked.

It's also got some sort of timing miss, seems to not like the default map. Gotta wait until 11 my time so I can call Procom.
I have nothing but Mac, and this is all set up for Windows...

I found that if my TPS was unplugged it mis fired like mad... so, for now its hooked up.

I'm not sure where I read it, but I think the TPS is supposed to be left connected with the Procomm. I have a similar engine to yours and I'm running #9. Not perfect, but close. I'm hoping to get a dyno soon so I can see what kind of hp I'm getting with the rev limiter at 8500.

I talked to the guy in the tech department at Procom today and he said if I've been running it this long with the TPS disconnected, to leave it disconnected. He also told me to run map 7, 8, or 9 for what I have modified. Now I need to get a pc with Windows over here, as these are not Mac compatible. He told me if I have any problems, just to call, he's there just about every day all week.

I'v had my tps unplugged for years. From what I had read on the rat forum lots of folks were running the procom with the tps disconnected with good results. Those running aftermarket carbs generally don't have access to a tps anyway. I had disconnected mine because of problems with my bike cuting off when it hit the rev limiter. Lately my bike had been missing on start up and tach acting up so I figured the cdi was getting ready to go hence my purchase of the procom unit. I'v only put a 100 miles on it with the procom so far. Its seems to run as well with no real issues except for a little longer warm up time.

Got my box put in today set it on download #9 what is the difference between a minor mod engine, generally mod engine, and an aggressively mod engine?

found this on pro com's web site
If you purchased a Procom CDI/ECU with the nine settings or that is fully reprogrammable, you can choose a setting based on your riding experience as well as aftermarket modifications. Please refer to the instruction sticker located on the back of our CDI/ECU.

* Think of a minor modified machine as one that has aftermarket parts that can easily be removed such as a slip on exhaust silencer, spark arrestor, etc.
* Think of a generally modified machine as one that has aftermarket modifications that are not very easy to remove such as full exhaust, air box, etc.
* Think of an aggressively modified machine as one that has aftermarket modifications that are permanent parts of your machine such as engine modification kits, dual exhaust, aftermarket clutch, etc.

Installed the Procom CDI the other day. Finally got to take it out for a ride today. What a difference. So far after my first ride it feels as though it was worth every penny. Set it on #6 ,it's like a different bike. Can not wait to get the time to play around one day and try a new program. Bike has K&N's ,rejetted, aftermarket freeflowing mufflers,and a few other mods.

I finally got my replacement unit installed today. The first one was faulty, the bike would not idle without shutting off, even at full operating temperature. I ran about 80 miles with the stock map on setting 4 for it's first trip. It seems somewhat sluggish when I whack the throttle, but it revs high and runs very smooth. I'm hoping to change the map to probably #9 tomorrow, need to go over to Dunnspeed's house since he has a windows pc. Hopefully it only gets better with a different map. The bike did shut off twice while I was out tonight at stop lights, don't know why it doesn't just act like a stock map.

I've got a Procom installed on an America w/904bb,Bub pipes, AI removed and a lightened flywheel by 2 lbs. Not sure which setting it is on but I had a dyno run with the stock map and map #10. Being somewhat heavyly modified I would've thought the #10 map would have produced the most HP. Not so, stock map produce 75.9 hp. Map #10 was a couple less.

Roadworthy I noticed my bike did die a couple of times also. Then I realized that it was not warmed up quite yet.I also noticed the idle was a couple of hundred rpm's lower.I set the idle speed back up and once it is warmed up it does not seem to have a problem with stalling at an idle.

Now running map #8. Not impressed yet, except with the high rev limit. I am loving that! Had #9 installed and it kept cutting off at idle. Don't know what's up with that. #8 still doesn't seem to run as hard as my stock box. Maybe I need to try #10, or call Procom and have them custom make a map for me.

So today I ran maps 6 and 10. I don't know what it is but the unit can not keep up with hard acceleration. Once it gets past 2500, 3000 rpms, it's really nice, but off the line it does not respond well. Kyle at Procom custom made a new map for me and sent it over, I'll get it installed here soon and see if it makes a difference. He seems to think the spark is too far advanced for the lower rpms, especially when I go from stop to WOT.

Cool. Shoot by when you can or maybe I'll run over there tomorrow.

2002 BA, Thunderbike pipes, stock everything else except for a couple of notches up on the main jets.

Jury is still out on this unit.. set it on 4 per the instructions and while the first test drive of around 50 miles was good, the next one gave me a starting issue after refueling (acted as though it were flooded) and died at stops twice and I too have a flickering neutral light at idle.
I have since readjusted and synched the carbs and while the garage test was good, I haven't ridden it since to confirm. Might try position 5 like Sixmil but hey, if it cuts out the decel pop, I guess it will just have to die at stops..

chy,

Same symptoms as both my procom cdis. Cinnamon Girl installs only. I adjusted the hals gap to .8mmm, yet have not re-installed the procom to check it out again.

Time for an install again. gonna try all the maps, baseline first.

Allrighty then.. having mediocre performance and some starting and idling issues on the recommended setting, today I got a bit more in depth..

I have an all bone stock 2002 bike except for Thunderbike pipes and I think I bumped the main jets up a couple of #'s when I installed the pipes.

I started by removing the tank and hooking up an alternate fuel source, then unbolted the cdi mounting bracket from the frame so I could see the numbers.

I adjusted and synchronized the carbs then I started at 0 and worked my way up..if it would start, I'd bring the rpms up to clear the cylinders then let it drop to an idle then blip the throttle. If it coughed or hesitated or seemed sluggish I moved on. If the response was okay I'd hold the engine at a good midrange rpm for about 5 seconds and listen for a nice even tone in the exhaust, blip the throttle then let it drop to an idle. If the exhaust tone seems to fluctuate or if it seems to stumble on the return to idle, you're not quite there.

I found my sweet spot on #8 and yes, I tried all the positions before settling in. This one gave me great response and smooth even roll from top to bottom.

From there I took it out on the road.. very nice, great torque all the way through the range, great response and solid idle. It pulls strong like it used to and has that delightful hi rpm power band that I love so. No low rpm bog or lag either.. however, I no longer have my beloved "pop,POP,pop from my pipes.... bummer that.

Starts good hot and I'll let y'all know about the cold starts when I can but for now, I'd say I've found my sweet spot... I s'pose time will tell.

You mean position 8 on this little blue switch?!

So how does the bottom end off the line compare to the stock CDI? Then right on through? I ask because it is the bottom end performance I have been hearing bad things about and I may be in the market for at least 1 CDI soon.

Ian, I am still in the process of getting mine dialed in, I have had pretty poor results so far unfortunately. I still have some things to try, need to run it with the TPS hooked up. I have a custom map made for my bike using the feedback that I have given them over the phone. With the maps provided I had poor throttle response in the low end, or not enough roll on power up top. I really wish this was a direct replacement for the stock ignitor program with a higher rev limit. Bouncing off the limiter was really the main reason I got one. Anyone having problems with cutting out at idle, or the neutral light flickering, or anything else, should really call Procom and talk to Kyle, every time I tell him about some issue that I think shouldn't be happening, he acts like I'm the only one that's ever said anything about it.

Make these guys aware of the issues so they can fix them!

I agree Dave, I would like a direct replacement with a little more top end RPM available. My bike is still pulling hard when it hits the limiter. I wonder why they set it where they did if higher RPM won't hurt anything and the engine is still pulling.

I'm tickled pink with the all around performance right now... idles good and runs great, no stumble or sag off the line. If the cold start/running condition is squared away as well, I'll be good to go.. now if only I could get back my decel popping.

SO is that two thumbs up for the Procom CDI unit??? Think I might be getting one soon!

I think the jury is still out, Chy and cold starts and Dave still tweeking.

Well, I think I finally got a winner here, custom map made by Kyle at Procom, TPS hooked up again, dial on #4. Nice smooth acceleration all the way through the range, pulls strong up to about 9 grand. Haven't needed to go any higher than that, really don't get up above 8500 much. Mostly when launching onto the highway. Lost a touch off the line, but I'll attribute that to the new 18 tooth front sprocket instead of the ignitor. I like it now.

I got one of the first Procoms when they first came out a couple years ago and installed in on my 06 790cc America. The results were awesome with the recommended settings and one of the few maps available at that time.

Then it started dying at stops and difficult cold starting. Eventually I returned it to Procom who promptly replaced it, I paid the shipping one way.

The replacement didn't seem as well put together as the original and displayed similar operating characteristics to the first one using the recommended settings.

At one point I had both the OEM and the Procom mounted under my tank and could switch the wiring harness between the two. The last time I tried to use it, it acted as though it was intermittently switching between 270 and 360 degree mode. I went less than a mile and switched back to my OEM CDI.

Later, after removing the Procom completely I hooked it up again trying different settings and apparently decided on #5 but I remember just starting the bike and letting it idle to see how long it would idle before shutting down. At first it was a couple minutes but finally it was less than 30 seconds so I concluded that there must be a heat problem and was thinking about a heat sink configuration but that was well over a year ago.

Since then I haven't put much time in working on the bike but more in riding. Also, I've thought about possibly there might be some low voltage issues the Procom is more sensitive to than the OEM after reading the threads about low voltage issues with our bikes but haven't followed through on that either.

Since reading CHY's post on the other thread about the gas pump incident and his revisiting his procom issue which seem to be common issues, I pulled mine off the shelf just to see what the last setting I used which was #5. The label on the back of the unit indicated that numbers 8, 9, and 0 are reserved for factory stuff so I never tried those.

I guess if I have a question in all this it would be, has the factory made some changes in the last couple years making #8 openly available on newer modules or do they still list #8 as a factory port? If not, I'll tinker with mine again and see if I can get it to function using the CHY technique plus I'll verify my voltage at the module. I would really like to get the thing working. I love the performance increases when it all gee haws just right. But even though I enjoy tinkering, I would rather be riding so I need something that is gonna stay the course for the long haul.

I'm not running down Procom. I'm grateful that somebody finally offered us an alternative to the OEM and the rev limits that shut us down just when its gettin good. But I also understand that when the tech is new there are bugs to be worked out. Its been a learning experience for me and there are factors I didn't previously consider mainly due to limitations in time and a greater desire to ride than to tinker. Sounds like from this thread that Procom has been working with most everyone and what issues arise have been easily resolved or maybe just lived with but thanks to CHy's gas pump incident I'm encouraged to give mine another go.

See, those issues are what I'm talking about. The guys at Procom kept acting like they had never heard of anyone else having idling problems. I really think more people need to contact them and make them make it right.

Well.. moving along to #6..
#8 worked great for the most part but the cold start and performance became an issue.
Since I've had this bike, it will spin over no more than 5 or 6 times before it either pops or starts now matter how long it has been sitting, but not anymore. Last week, it was only in the 50's and I had a bit of a time starting up cold. I never spin the engine for more than 10 seconds at a time.. (10 secs on, 30 secs off) and was on near the end of my second go round before it popped off... hmmmm says I.

Yesterday afternoon I again had some difficulty getting it started when I pulled it out of the shed. Again it had to spin over many times before finally firing up so I thought this morning would be better as I had run it yesterday but that was not so. Granted , it was a bit chilly but I have ridden that bike in much colder temps and never had an issue.

It spun through 2, 10 sec. cycles without so much as a pop.. while on my 30 second break on the second go round, I detected the smell of raw fuel so I pushed in the choke at which time it tried to fire up but it took me several more attempts to get it running enough so I could slowly engage the choke to get her to smooth out.

Stumbles galore for the first 5 miles everytime I would roll on power till I finally got out on the open road. I had to stop a couple of times to warm my hands on the jugs but left it running both times. At the second stop however, it stalled as I attempted to pull back into the road and started back with some difficulty.

At my rest stop at 76/60, I let it sit for about 15 to 20 minutes as I warmed up a bit and again it had to spin for some time before firing up and then stalled immediately afterward. At this point I didn't feel so good about that long lonely trip up 68 to Tellico by myself so i opted for the road back home.

This afternoon Nemo came by and we tweaked some more with the procom.. again, #6 this time, so far so good but we'll see whats what when it gets a bit cooler.

Having the same problems Chy. As the temps drop its getting more and more difficult to start. Installed mine over the summer and it had mostly been doing fine. Minor issues with starting but now its getting really difficult.

I have been following this thread for quite awhile and have a few comments and questions. If I ever get time to install the 904 kit on my 03 I was just going to go with the Triumph Twin ignitor upgrade. It seems like there are very few complaints about these units so I have to assume the reliability is good. I just wonder why I would need all the different settings available with the Procom unit. These are not race bikes and reading the comments on this thread most of those settings are useless not to mention the starting problems that seem to pop up for many of the users. I would appreciate comments, am I way out to lunch here or just missing something.
